Can I use ForeFlight Mobile to file a flight plan into the DC FRZ?

While you can use ForeFlight Mobile to file a flight plan to an airport in the DC SFRA (by selecting DC SFRA flight plan type on File & Brief) flights into the FRZ cannot be filed electronically using ForeFlight Mobile, or any other civilian app/online service.

You can contact the Washington Hub FSS at 866-225-7410, or Lockheed Martin Flight Service at 1-800-992-7433 to file a flight plan into the FRZ.
